Description

차량용 동력전달장치{POWER TRANSMISSION DEVICE FOR VEHICLE}POWER TRANSMISSION DEVICE FOR VEHICLE

본 발명은 차량용 동력전달장치에 관한 것이며, 더욱 상세하게는 부품수의 축소가 가능한 차량용 동력전달장치에 관한 것이다. The present invention relates to a power transmission device for a vehicle, and more particularly, to a power transmission device for a vehicle capable of reducing the number of parts.

일반적으로 차량용 토셔널 댐퍼(Torsional　damper, Dual mass flywheel 이라고도 함)는 차량의 엔진과 변속기 사이에 설치되어 동력전달 과정에서 발생하는 비틀림 진동을 감쇠시키는 기능을 갖는다.In general, a torsional damper for a vehicle (also called a Torsional　damper, dual mass flywheel) is installed between an engine and a transmission of a vehicle and has a function of damping torsional vibrations generated during power transmission.

도 1에는 종래 차량용 토셔널 댐퍼가 도시된다. 종래 차량용 토션 댐퍼는 변속기 외측에 설치된 차량 엔진의 출력축(1)에 결합되는 플라이휠(2)의 축 방향에 상대 회전 가능하게 배치되는 드라이브 플레이트(3)와, 플라이휠(2)과 드라이브 플레이트(3) 사이에 설치되는 토셔널 스프링(4)을 포함한다. 1 shows a torsional damper for a conventional vehicle. A torsion damper for a conventional vehicle includes a drive plate 3 rotatably disposed in an axial direction of a flywheel 2 coupled to an output shaft 1 of a vehicle engine installed outside a transmission, a flywheel 2 and a drive plate 3 It includes a torsional spring (4) installed between.

그런데, 종래의 차량용 토셔널 댐퍼는 변속기의 외측에 설치되고 토셔널 댐퍼 자체가 별도의 부품이기 때문에, 변속기의 전장을 많이 차지하는 문제가 있었다. 특히 진동소음(NVH, Noise, vibration, harshness) 성능 강화(저강성)를 위해 코일 스프링의 중심경(Rm)을 증대시켜야 하므로 변속기의 전장 축소에 어려움이 있었다. 또한 종래 차량용 토셔널 댐퍼의 경우 작동각도가 커서 마모가 발생할 수 있으므로 이를 방지하기 위해 별도의 마모방지 구조가 적용된다. However, since the conventional torsional damper for a vehicle is installed outside the transmission and the torsional damper itself is a separate part, there is a problem that takes up a lot of the overall length of the transmission. In particular, it was difficult to reduce the overall length of the transmission because it was necessary to increase the central diameter (Rm) of the coil spring in order to strengthen the performance (low rigidity) of noise, vibration, harshness (NVH). In addition, in the case of a conventional torsional damper for a vehicle, a separate abrasion prevention structure is applied to prevent abrasion due to a large operating angle.

따라서 변속기의 전장을 축소시키면서 마모를 방지할 수 있는 차량용 토셔널 댐퍼가 필요한 실정이다. Accordingly, there is a need for a torsional damper for a vehicle capable of preventing wear while reducing the overall length of the transmission.

본 발명의 배경기술은 대한민국 공개특허공보 제2009-0020791호 (2013. 12. 03. 공개, 발명의 명칭: 하이브리드 차량용 동력전달장치)에 게시되어 있다.Background art of the present invention is published in Korean Patent Publication No. 2009-0020791 (published on Dec. 03, 2013, title of invention: power transmission device for hybrid vehicle).

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 토셔널 댐퍼부가 변속기의 내부에 위치함으로써, 변속기 내부의 오일을 이용하여 마모를 방지하는 차량용 동력전달장치를 제공하는 것을 목적으로 한다.The present invention has been devised to solve the above problems, and an object of the present invention is to provide a power transmission device for a vehicle in which a torsional damper part is located inside a transmission, thereby preventing wear by using oil in the transmission.

또한, 본 발명은 토셔널 댐퍼부의 마모를 방지하기 위한 부품들을 생략 가능하여 부품수를 축소시킬 수 있는 차량용 동력전달장치를 제공하는 것을 목적으로 한다.Another object of the present invention is to provide a power transmission device for a vehicle capable of reducing the number of parts by omitting parts for preventing wear of the torsional damper part.

상기 목적을 달성하기 위해, 본 발명에 따른 차량용 동력전달장치는 동력을 생성하는 엔진부와, 전달축부를 통해 상기 엔진부로부터 동력을 전달받아 변속하여 출력하는 변속부와, 상기 변속부의 내부에 설치되고, 상기 전달축부의 회전 방향으로 작용하는 충격과 진동을 흡수하는 토셔널 댐퍼부를 포함하는 것을 특징으로 한다. In order to achieve the above object, a power transmission device for a vehicle according to the present invention includes an engine unit for generating power, a transmission unit receiving power from the engine unit through a transmission shaft unit and outputting the speed by shifting, and is installed inside the transmission unit and a torsional damper for absorbing shocks and vibrations acting in the rotational direction of the transmission shaft.

상기 변속부는 모터부를 포함하고, 상기 모터부는 모터하우징과, 상기 모터하우징의 내부에 설치되고 회전 가능하게 구비되는 로터부와, 상기 전달축에 직간접적으로 결합되고 상기 로터부를 지지하는 로터지지부를 포함하고, 상기 토셔널 댐퍼부는 상기 로터지지부에 장착되는 것을 특징으로 할 수 있다. The transmission unit includes a motor unit, and the motor unit includes a motor housing, a rotor unit installed in the motor housing and rotatably provided, and a rotor support unit coupled directly or indirectly to the transmission shaft and supporting the rotor unit. and the torsional damper part may be mounted on the rotor support part.

상기 토셔널 댐퍼부는 상기 전달축부의 축 방향을 따라 직렬로 배치되는 제1 댐퍼부재와, 제2 댐퍼부재를 포함하는 것을 특징으로 할 수 있다.The torsional damper part may include a first damper member and a second damper member disposed in series along an axial direction of the transmission shaft part.

상기 제1 댐퍼부재는 상기 로터지지부에 결합되는 제1 리테이닝 플레이트와, 상기 제1 리테이닝 플레이트의 원주 방향으로 다수 개가 배치되어 탄성력을 제공하는 제1 댐퍼스프링과, 상기 전달축부에 직간접적으로 결합되고, 상기 제1 댐퍼스프링의 반력에 의해 회전하는 제1 드라이브 플레이트를 포함하는 것을 특징으로 할 수 있다.The first damper member may include a first retaining plate coupled to the rotor support, a plurality of first damper springs disposed in a circumferential direction of the first retaining plate to provide elastic force, and directly or indirectly to the transmission shaft portion. It may be characterized in that it comprises a first drive plate that is coupled and rotates by the reaction force of the first damper spring.

상기 제2 댐퍼부재는 상기 제1 드라이브 플레이트에 결합되는 제2 리테이닝 플레이트와, 상기 제2 리테이닝 플레이트의 원주 방향으로 다수 개가 배치되어 탄성력을 제공하는 제2 댐퍼스프링과, 상기 전달축부에 직간접적으로 결합되고, 상기 제2 댐퍼스프링의 반력에 의해 회전하는 제2 드라이브 플레이트를 포함하는 것을 특징으로 할 수 있다.The second damper member includes a second retaining plate coupled to the first drive plate, a plurality of second damper springs disposed in a circumferential direction of the second retaining plate to provide elastic force, and directly or indirectly to the transmission shaft portion. It may be characterized in that it comprises a second drive plate coupled to the positive and rotating by the reaction force of the second damper spring.

본 발명에 따른 차량용 동력장치는 토셔널 댐퍼부가 변속기의 내부에 위치함으로써, 변속기 내부의 오일(Automatic Transmission Fluid, ATF)을 이용하여 마모를 방지할 수 있는 이점이 있다. In the power device for a vehicle according to the present invention, since the torsional damper part is located inside the transmission, it is possible to prevent wear by using automatic transmission fluid (ATF) inside the transmission.

이에 의해 본 발명은, 종래 건식 타입에서 토셔널 댐퍼부의 마모를 방지하기 위한 부품들을 생략할 수 있으므로, 부품수를 축소시킬 수 있다. 또한 본 발명은 부품수를 감소시킬 수 있으므로 전장을 축소시키는 효과를 제공할 수 있다. Accordingly, in the present invention, since parts for preventing wear of the torsional damper part can be omitted in the conventional dry type, the number of parts can be reduced. In addition, the present invention can provide the effect of reducing the overall length since it is possible to reduce the number of parts.

엔진부(200)는 내연기관의 구동에 의해 동력을 생성하는 장치이다. 미설명부호인 210은 엔진부(200)의 출력축이다. The engine unit 200 is a device that generates power by driving an internal combustion engine. Reference numeral 210, which is not described, denotes an output shaft of the engine unit 200 .

변속부(300)는 전달축부(301)를 통해 엔진부(200)로부터 동력을 전달받아 변속하여 출력한다. 구체적으로 엔진부(200)에서 생성된 동력은 전달축부(301)를 통해 변속부(300)에 전달되어 차량이 주행되게 할 수 있다. 전달축부(301)는 축 형상으로 구비될 수 있고 동력전달 과정에서 회전되게 구비될 수 있다.The shift unit 300 receives power from the engine unit 200 through the transmission shaft unit 301 and shifts the power to output it. Specifically, the power generated by the engine unit 200 may be transmitted to the transmission unit 300 through the transmission shaft unit 301 to cause the vehicle to run. The transmission shaft part 301 may be provided in a shaft shape and may be provided to rotate during the power transmission process.
